Description

Head with very prominent ridges, namely a canthal, a slight preorbital, a supraorbital, a postorbital, a parietal, and an orbitotympanic; parietal ridges obliquely directed inwards; snout short, blunt; interorbital space broader than the upper eyelid; tympanum distinct, two thirds the diameter of the eye. First finger extending beyond second; toes half webbed, with single subarticular tubercles; two moderate metatarsal tubercles; no tarsal fold. The tarsometatarsal articulation reaches between the eye and the tip of the snout. Upper surfaces covered with irregular warts; parotoids moderately elongate, elliptical, very prominent. Uniform brown above; beneath marbled with brown. Male with a subgular vocal sac.[3]

gollark: A quadratic is a polynomial of degree 2.
gollark: The "degree" is the maximum amount of variables multiplied together in a monomial; 3 there, because x³ is xxx.
gollark: A polynomial is basically something like x³ + xy² + x + 7; the sum of some monomials, which contain variables and stuff multiplied together.
gollark: Plus trigonometry and exponentials are conveniently merged.
gollark: For example, they have the "fundamental theorem of algebra", where a polynomial of degree n *always* has n roots.
